Hydrogen could be blended with natural gas to heat British homes within the next three years in a bid to reduce pollution, the Government is expected to announce tomorrow. That would mean that by 2023, 20pc of the gas in pipelines across the country would actually be made up of hydrogen. The commitment to hydrogen, alongside funding for a new nuclear power plant in Suffolk, further support for onshore and offshore wind and solar, and a ban on the sale of new petrol and diesel cars in the next decade, is expected in a 10-point plan that Boris Johnson is due to unveil on Wednesday. Blending natural gas with hydrogen has already been widely tested. A 20pc hydrogen mix means households would not have to change boilers or other appliances. But the Energy Networks Association (ENA), which represent gas distributors, has also been working with boiler manufacturers to develop a boiler that is ‘hydrogen-ready’. Since 2002, gas network distributors have been replacing old Victorian gas pipes with plastic ones. Around 80pc of the country’s pipes have now been replaced, meaning that they can accommodate hydrogen. Blue hydrogen is twice as expensive as natural gas, and green hydrogen is four times as expensive.
